Diffraction of transmission light through triangular apertures in array of retro-reflective micro-prisms

, 2012
The array of micro-prisms was described by model of multi-period blazed gratings consisting of triangular apertures. The origins of hexagram-shaped diffraction patterns were interpreted based on multiple-beam interference and diffraction array theorem ...

Quantum Hall effect induced by electron-phonon interaction

, 2020
When phonons couple to fermions in 2D semimetals, the interaction may turn the system into an insulator. There are several insulating phases in which the time reversal and the sublattice symmetries are spontaneously broken.

An Improved Data Processing Algorithm for Spectrally Resolved Interferometry Using a Femtosecond Laser

Sensors
Spectrally resolved interferometry utilizing a femtosecond laser is widely employed for absolute distance measurement. However, deviations in the output time pulse of the conventional algorithm through inverse Fourier transform are inevitable. Herein, an

DC‐Driven Fractional Flux Quanta in Two‐Band Superconductors

physica status solidi (RRL) – Rapid Research Letters, Volume 19, Issue 12, December 2025.
The dc‐driven distancing of fractional flux quanta is theoretically analyzed for a dual‐band superconductor with a periodic pinning potential. The analysis is based on the dynamical equation of motion for a single composite vortex. The model neglects the phase difference between the condensates and may be applicable to two‐band superconductors with ...
